History of Roulette — From 18th-Century Paris to Online Tables

Roulette has been spinning for over three centuries, and the version played on casino floors today is recognisably close to the game that attracted gamblers in 18th-century Paris. Few casino games can claim that kind of continuity. The wheel has been refined, the zeros redesigned, and the table moved from private salons to digital screens, but the fundamental act — a ball orbiting a spinning wheel, settling into a numbered pocket — has not changed. That durability is partly aesthetic, partly mathematical: roulette is simple to understand, impossible to truly master, and perpetually watchable.

Origins — Pascal, and the birth of the wheel

The word “roulette” is French for “little wheel.” The game’s immediate ancestor is widely credited to the French mathematician and philosopher Blaise Pascal, who in 1655 attempted to construct a perpetual motion machine — a device that would keep spinning indefinitely without an external energy source. Pascal’s device failed as a perpetual motion machine, as all such devices must by the laws of thermodynamics, but the spinning wheel it left behind attracted the attention of gamblers.

By the late 17th and early 18th centuries, games using a numbered wheel had become established in Paris. Descriptions from the 1720s and 1730s reference a game that combined a spinning wheel with a numbered betting layout resembling what we would now recognise as roulette. The wheel at this stage was not yet standardised: the number of pockets, the placement of zeros, and the house rules varied between establishments.

Other historians have traced elements of early roulette to two older games: Hoca, an Italian and French parlour game involving a spinning device, and E.O. (“Even-Odd”), a popular 18th-century English wheel game with even and odd outcomes. The exact genealogy is unclear, but by the mid-18th century, a recognisable form of roulette — numbered wheel, betting layout, house advantage — was an established feature of Parisian gambling culture.

The Blanc brothers and the single-zero wheel

The pivotal moment in roulette history occurred in 1843 in Hamburg, Germany. Two Frenchmen — François and Louis Blanc — were operating a casino there and were looking for an edge in a competitive market. Casinos of the era typically offered a double-zero wheel, with both 0 and 00 as house pockets. The Blanc brothers made a bold commercial decision: they introduced a single-zero wheel, cutting the house edge roughly in half and offering players significantly better odds than any competitor.

The single-zero game was a success. Players sought out the Blanc casino precisely because the odds were better, and the volume of play more than compensated for the reduced edge on each spin. The game spread across Europe under the name “French roulette,” the single-zero format becoming the continental standard.

François Blanc later secured the franchise to operate the casino in Monte Carlo, then a tiny principality seeking to repair its finances. The Monte Carlo Casino opened in 1863 and became, over the following decades, the most famous gambling establishment in Europe. The game of roulette, already associated with European elegance, became inseparable from the Monte Carlo image: evening dress, high stakes, and the turning wheel.

A famous piece of Monte Carlo lore from this era is the story of Joseph Jaggers, a British engineer who in 1873 hired a team of clerks to record outcomes at the Monte Carlo roulette tables over several weeks. Jaggers was looking for physical wheel bias — a slight imperfection in manufacture that made certain pockets come up more frequently than randomness predicted. He found it, and he backed the biased numbers heavily over several days, reportedly winning a substantial sum before the casino identified and remedied the problem. Whether the story is entirely accurate is debated, but it illustrates a real vulnerability of mechanical roulette wheels that casinos have worked to eliminate ever since.

American roulette — the double-zero endures

The single-zero reform did not travel uniformly. In the United States, where gambling had arrived with European settlers and developed independently along the Mississippi River and in frontier towns, the double-zero wheel remained standard. American casinos retained 0 and 00 — and some wheels of the early 19th century added a third house pocket, the American eagle, before the market settled on the two-zero format that persists today.

The reason for American roulette’s durability is partly commercial inertia and partly the nature of the American casino market, where volume and variety mattered more than offering the best odds on any single game. The double-zero wheel with a house edge of 5.26% remained standard in Nevada after casino gambling was legalised there in 1931, and it has been the American default ever since.

The divergence between European and American roulette — one zero versus two — is the most consequential practical difference in the game. It doubles the house’s advantage and is the primary reason experienced players in the United States seek out single-zero tables where available.

The 20th century — from casinos to screens

Roulette’s 20th-century history is largely a story of geographic spread and, eventually, digitisation. The game remained closely associated with European high society through the early part of the century, fed by the Monte Carlo mystique and later by the glamour of Cannes, Deauville, and Baden-Baden. The association was reinforced by fiction: roulette appears in the works of Dostoevsky — who wrote The Gambler (1866) partly from personal experience of losing at the wheel in Wiesbaden — and became a standard prop for elegant tension in 20th-century films.

Atlantic City legalised casino gambling in 1978, bringing roulette to the American east coast. By the 1980s and 1990s, the game was a fixture on casino floors globally, from Macau to Sun City to newly deregulated European markets.

The internet changed the game’s delivery without changing the game itself. Online roulette using a random number generator appeared in the late 1990s with the first wave of online casinos. The early versions were simple software simulations, but they made the game available to anyone with a connection, at any hour, without requiring travel to a physical casino.

Live dealer roulette, which streams a human croupier at a real wheel in real time, emerged in the 2000s and grew significantly through the 2010s. It resolved the main objection to purely digital roulette — that an RNG feels different from a physical wheel — by delivering the social and mechanical texture of the real game over a digital connection. Live dealer tables now account for a substantial share of online roulette play globally.

Today, roulette exists simultaneously in its original form — the same single-zero wheel François Blanc introduced in 1843, at felt tables in Monte Carlo and hundreds of other casinos — and as a digital experience available to any player on any device. The game that emerged from a mathematician’s failed experiment more than three centuries ago shows no sign of losing its place at the centre of casino culture.
